Ma Calipers a Vernier Oyezera Pulasitiki a 150MM

Vernier caliper ndi chida choyezera kutalika, m'mimba mwake ndi kunja. Vernier caliper imapangidwa ndi chitoliro chachikulu ndi vernier chomwe chimatha kutsetsereka pa chitoliro chachikulu. Sikelo yayikulu nthawi zambiri imakhala mu mm, pomwe pali magawo 10, 20 kapena 50 pa chitoliro. Malinga ndi kugawa, chitoliro cha vernier chingagawidwe m'magawo 10 a vernier caliper, magawo 20 a vernier caliper, magawo 50 a vernier caliper, ndi zina zotero. Chitoliro chokhala ndi magawo 10 ndi 9mm, magawo 20 ndi 19mm, ndipo magawo 50 ndi 49mm. Pali mapeyala awiri a zitoliro zoyezera zosunthika pa chitoliro chachikulu ndi chitoliro cha vernier caliper, chomwe ndi chitoliro choyezera chamkati ndi chitoliro choyezera chakunja. Chitoliro choyezera chamkati nthawi zambiri chimagwiritsidwa ntchito kuyeza m'mimba mwake wamkati, ndipo chitoliro choyezera chakunja nthawi zambiri chimagwiritsidwa ntchito kuyeza kutalika ndi m'mimba mwake wakunja.

Vernier caliper ndi chida chomwe chimagwiritsidwa ntchito kwambiri poyezera kutalika m'mafakitale. Chimakhala ndi thupi la wolamulira ndi vernier yomwe imatha kutsetsereka pa thupi la wolamulira. Mukayang'ana kumbuyo, cholozera chimakhala chonse. Pali chidutswa cha kasupe pakati pa vernier ndi thupi la wolamulira, ndipo mphamvu ya kasupe ya chidutswa cha kasupe imagwiritsidwa ntchito kupangitsa vernier ndi thupi la wolamulira kukhala pafupi. Pali screw yomangirira pamwamba pa vernier, yomwe imatha kuyika vernier pamalo aliwonse pa wolamulira. Thupi la wolamulira ndi vernier zonse zili ndi zikhadabo zoyezera. Zikhadabo zoyezera zamkati zingagwiritsidwe ntchito kuyeza m'lifupi mwa groove ndi m'mimba mwake wamkati wa payipi, ndipo zikhadabo zoyezera zakunja zingagwiritsidwe ntchito kuyeza makulidwe a ziwalozo ndi m'mimba mwake wakunja wa payipi. Wolamulira wakuya ndi wolamulira wa vernier zimalumikizidwa pamodzi kuti ziyeze kuya kwa groove ndi mbiya.
